the class used for heating purposes; Aand its object is to provide means for economically burning heavy or crude oil for heating boilers of ,various kinds.

To this.end,.our, invention consists in the construction and combinationof parts formhereinafter more fully described, and particularly lset forth in the claims, reference being had to the 'accompa Anymg drawings in which; l

f V'Figure 1 represents our oil burner in centra-l, longitudinal-section. Fig. 2 shows a cross section at line m of Fig. 1. Fig. 3 shows al cross section at line y, and Figs. 4 and 5 are 'det-ail views, in longitudinal section, of the delivery mouth, showing different adjustments of the lips.

Numeral 1 represents` ai steam pipe joined ,at ,one end with a steam coupling, 2, and at the other end with va ca 3. A packing-box, f1, is provided with a g and, 5, and packing, 6, to form a stream tight joint around the o il pipe, 7, which is fitted to slide longitudinally A binding screw, 8, secures the pipe'atany point of adjustwith an oil supply p1pe, 10, is provided with a .packing-box, 1'1, having a gland, 12, and

rod is.screw-threaded at 15, through the p`acking-box, and is provided with a handu'heel, 1G. The valve-roddel, passing longitudinally through the oil pipe, 7, carries a retort, 17, into 'which or through which it is screw-tlneaded; and a binding nut, 18, secures it' rigidly to the retort. The inner end, 19, of the retort is neat-ly lfaced as a valve to seat against the end of the cap, 3; the annular opening, 20, between retort and cap being for the discharge of oil gas in service. A throttle-valve,4 2l, is secured upon the inner end of the oil p ipe, 7, and has"`^fia`nged heads, 22, 23. and 1s fitted to n Specification of Letters tent. A Application led November 25, 1908.

reciprocate longitudinally wit-hin the retort, 17,l and is faced to engage the cap, 3, as a seat and it has a reduced body, 24,' leaving an expansion chamber, 25, for gas around it I These flanges are perforated with holes, 26, which should not be in line through the two flanges, be-

cause the object .of't-heseflanges-is.` to ob-` struct the free passage of oil 'through the Patented Aprn'zo, 1909. i

retort,1 retaining it t-herein to become as highly heated as possible, thus expanding it into gas for combustion. lSteam jet holes, 2T, are bored 'through the cap, 3. These jets are preferably arranged inconical form forming a ring' of discharge openinvs for the steam. A ring, 2S, screw-threade upon the cap, 3, and av ring, 29, screw-threaded upon the retort, 17 are shaped at vtheir adjacent-edges, as lips outside of the mouth, 30, Where the combined steam and oil gas is delivered for combustion. The steam'supply pipe, 31, and the oilsupply pipe, 10, may be provided with the usual valves (not shown) for stopping or limiting the flow through them.

In operation, oil passing through the pipe, 7, enters the retort, 17, and is vaporized by the surrounding heat. The vapor asses into chamber,.25, where it is ex ande into gas. lThence 1t passes through ioles, 26, to-l ,l 5 2, l, the annular outlet, 20, where 1t 1s niet bv I .steam from the jets, 27, and the gas and steam mixing, rush out at the mouth, 30, where instantaneousl combustion takes place, 'the flamebeing-directed by thc.lips, 28, 29,

yaccording to their adjustment. If they are setwell forward, asin F 4f, the flanle will be delivered around the retort); if they are .t se to bring the mouth, 30, opposite to the annular de Very, 2U, asin Fig. `5, the flame will 'be delivered 1n a circle. The burning of crude oil as a fuel being yetl in the er-- periinental stage, this burner is designed 'with these Various adjustments to adapt it to' produce the best trcsults with eachygrade of oil. To this end, the adjacent edges ot' the lips may be made more or less angular, and with either straight or curved faces see Figs. 1 and 4, and they may be adjusted for 4Wide delivery or for narrow delivery; and central, or forward or backward; and when the best result is ascertained with any grade of oil the lips for that service I nay be one or both, made as integral portlons of their respective supports, the cap, 5A, andL Wheel 16, is located in the open air so thatthe retort may be operated asavalve to adjust the dischar e opening, 20, while heat is on inservice. he throttle-valve, 21, may also be adjusted While heat is on, by means of its supporting pipe, 7, Which extends into open air; the pipe, l0, swinging enough to permit the little movementrequired For experimental purposes; for adaptation to different densities and other variations in oils; for maintaining the best results when once secured; and for adjustment to compensate for Wear and for fouling in service, this invention presents the qualifications described.

Having thus fully described our invention, what We believe to be new and desire to secure byLetters Pat-ent is the following claims.

l. In oil burners, a steam pipe; a cap thereon perforated to form a rino of discharge jets; an oil pipe Within the steam pipe and passing through the said cap; a valve-rod Within the oil pipe and extending out at both ends thereof; a retort secured upon the valve-rod and faced at one end` as a valve; the aforesaid cap faced as a seat.

' for the said valve, and means for reciprocating the valve-rod longitudinally through the oil pipe.

2. In oil burners, a steam pipe; a cap thereon having a series of perforations arranged in a ring and faced Within thering as a valve-seat; a valve-rod passing, longitudinally through' the steam pipe and carrying a retort; means for reciprocating the valve-rod, and means for delivering oil to the retort.-

3. In oil burners,a steam ipe;a cap .thereon having a series of per orations arranged in a rmg; an oil pipe within thev steam pipe and tted to reciprocate longitudinally through it and projecting at both ends therefrom; a retort around the end of lthe oil pipe beyond the cap; and -a throttlevalve upon the end of the oil pipe Within the retort 'to engage the end of the saidrcap.

4, In oil burners, a steam pipe; a cap thereon havinga series of perforations larranged in a ring; an' oil pipe Within'the v cap; a throttle-telve secured upon t steam pipe and fitted to reciprocate throuvh it; a retort around the oil pipe'be ond the e end of the oil pipe to engage the -end of the said l' cap and having flanved heads and fitted ,to reciprocate Within the said retort.

5. In oil burners,` a steam pipe having discharge outlets near its circumferenceat one entf; an oil pipe Within the steam ipe and projecting beyond its delivery en g a ret-ort over the endV of the oil pipe and having an annular discharge adjacent to the steam pipe discharge; and a throttle valve mounted upon the oil pipefA and having flanges fitted within the-fretort, each flange having a series of apertures'through it 'for' the passage of oil'.

(5. In oil burners, a steam pipe discharging substantially in a circle at one end; an oil pipe Within the steam pipe and 4project- `ing beyond the end thereof; a retort around the oil pipevand having a circumferential discharge at the end of the steam pipe; a lip around the delivery of the steam pipe and longitudinally adjustable thereon, and a lip longitudinally adjustable upon' the retort.

7. In oil burners, a steam pipe fitted to discharge substantially in a circle at its end; a' retort having circumferential "delivery adjacent to the steam delivery; a pipe for delivering oil into the retort, and lips beyond, and surrounding the said deliveries and forming a mouth for the discharge of their united product. y

l8. In oil burners, a steam pipe; an oil pipe; a retort connected Withthe latter; the discharge outlets for the steam pipe and for the retort being located in adjacent rings V nesses.
